Authentication

ValidonX supports two authentication modes depending on whether the caller is your backend (use an API key) or an end-user client running on a device (use a bearer token). Both share the same rate-limit and error model.

Pick the right credential

• Overview — when to use API keys vs bearer tokens, and the trust model behind each
• API Keys — long-lived credentials for server-to-server partner integrations
• Bearer Tokens — short-lived tokens for end-user clients (apps, CLIs, IDE plugins)

Operational details

• Rate Limits — the per-key + per-tenant ceilings, and how to read the rate-limit headers
• Error Handling — auth-specific error codes and what each one means in practice

Where to next

Once your credentials are working, head to the Integration API overview for the endpoint surface, or Guides for deeper conceptual material.
